Some European barrels are made with choke towards the muzzle.
Choke prevents increased gas blow by as the bullet passes through the barrel getting more and more worn. Reduced gas blow by towards the muzzle reduce barrel wear due to the "blow torch effect". This is scientifically proved by GIAT and the French FRF1 and FRF2 have choked barrels.
Choked barrels are also less affected by fouling in front of the chamber, that can "damage" the bullet, because the bullet is "resized" towards the muzzle". Choked CF barrels will not win any high end BR comps but will usually outperform "straight" barrels in long shooting sessions between cleaning and in "dirty" field conditions, especially as total barrel round count goes up.
In addition, my personal experience, is that choked barrels "resize" bullets and increases accuracy with "poor" ammo like milsurp.
Schultz&Larsen match and hunting barrels, with cut rifling, are choked during lapping. S&L has a stellar reputation in Europe and in Scandinavia S&L outsells LW by at least 100-1 in match barrels.
Other makers I think have choked barrels are Anschutz match 22lr and Steyr(SSG).
Are there any US barrels with choke?
